ANTENNA FOR USE WITH RADIO SETS.

Application filed June 14, 1926.

This invention relates to certain new and useful improvements in antenna for use with radio receiving sets, and pertains more particularly to an antenna of the loop type.

The primary object of this invention is to provide an improved antenna of the above mentioned character having an increased receiving area.

Another object of this invention is to provide an antenna the receiving surface of which is composed of a plurality of independent elements.

Another object of this invention is to pro vide an antenna, the receiving surface of which is composed of a plurality of independent substantially radiating elements.

A further object of this invention is to provide an antenna which is simple in construction, efiicient and compact in use and which may be economically manufactured.

In the drawings Figure l is a top plan view of the im proved antenna, and

Figure 2 is a side elevation of the same.

Referring in detail to the drawings, A designates generally a preferred type of antenna constructed in accordance with my invention, and which is composed of a series of frames B, each of which is formed of a single piece of wire bent into open rectangular form. Each of the frames are further formed to provide a depending support 1 at their inner ends, which when placed together, are adapted to be engaged by a band 2 or other suitable clamp for securing the frames in the form shown in Figure 1,

and to support the same in a vertical position upon a post 3 or other support. The outer ends of the frames are held in set up position by means of a continuous brace Wire l as shown in Fig. 1, which encircles the frames and is coiled at 10 about the outer ends of each of the frames.

Each of the frames is provided at their opposite ends with a series of insulators 5, through which a continuous wire strand 6 is alternately threaded thereby to afford a zig-zag formation.

One end 7 of the wirestrand of each frame is secured to the uppermost insulator and is spaced from the remaining portion of the frame, while the lower end 8 of the strand is twisted together with the lower ends of the strands mounted upon the, remaining frames, whereby to provide a single Serial No. 115,931.

conductor 9 which is adapted to be secured to a radio apparatus.

Wires 11 are threaded through the insulators 5 and are twisted and received in holding notches 12 in the ends of frame so as to hold the insulators against vertical movement.

From the foregoing it will be apparent that a simple, compactand easily manufactured device is provided and one which has a large receiving area confined in a small space.

Vhat is claimed is 1. An antenna for radiotelegraphic use, including a support, a plurality of radiating substantially rectangular frames disposed vertically upon the support, spaced insulators carried by each of the ends of the frames, a conducting element passed alter nately through the insulators from one end to the other of each of the frames whereby to afford an increased conducting area for each of the frames, means to insulate the upper ends ofthe conducting elements from each other, and means to secure the lower ends of the conducting elements together to form a single conductor.

2. An antenna for radio-telegraphic use, including a support having a socket, a plurality of radiating substantially rectangular. frames, spaced insulators carried by the inner and outer ends of the frames, a conducting element passed alternately through the insulators from one end to the other of each of the frames to afford an increased conducting area for each of the frames, means to insulate the upper ends of the conducting elements from each other, means to secure the lower ends of the conducting elements together to form a single conductor, and depending arms formed on the inner ends of the frames to engage in the socket of the support to retain the frames in a vertical position.

3. An antenna for radio-telegraphic use, comprising a plurality of rectangular frames, a series of insulators mounted. upon the opposite ends of the frames, and conducting elements passed continuously through the insulators from top to bottom of the frame the upper ends of said elements being insulated from each other and the lower ends thereof being secured together to form a single conductor.

In testimony whereof I afliX my signature.
